Youre lucky- if the damagie had been less they could have repaired/reprinted it and never told you....

Have they offered to explain the calculus behind '14 days'?

Yeah, the 14 day delay estimate seemed overly optimistic to me. I'm going to contact BMW corporate today and see what their take on it is. This situation also sucks because the rear tires on my current 135i have EXACTLY 4/32nds of tread left. Now...if I have to drive my current car an extra couple of weeks and those treads become a lease return issue, I hope BMW will cut me some slack. That's another issue I'll bring up with corporate today.
